The hydrodynamics of a free, liquid jet and their influence on direct contact heat transfer—II Conditions of change of liquid outflow type through sharp inlet edged orifice

Abstract

Liquid can flow through a sharp inlet edged orifice occupying total orifice cross-section area without wetting at all or with partial wetting of inner walls of the aperture. In the present paper an influence of individual parameters on the flow type and possibility of the phenomenon of hysteresis to occur have been discussed. A dimensionless equation was proposed which can be helpful in forecasting a change in the type of outflow in given conditions.
